SPEEDAIRE air-powered needle and chisel scalers are pneumatic tools, designed to clean dirt, rust, mill scale and paint from a surface. These scalers feature inline construction with an ergonomic holding design, helpful for reaching through openings and into recesses or tight spaces. They are equipped with a removable retainer which can be replaced with a bundle of needles or a chisel and a thumb control lever to easily operate the scaler. The needle bundle is loosely tied for cleaning applications while chisels help in breaking through heavy deposits. Choose from a wide range of these air-powered needles and scalers, available in 4000 and 4400 BPM (blows per minute) ratings on Raptor Supplies.
